The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the repair and modification of a specific generator, identified by NSN 7R-6115-016432102-QE, with a quantity of 55 units required. This procurement is critical as the item is flight critical, necessitating Government source approval prior to contract award, and the technical data required for competitive solicitation is not available. Interested parties must submit their proposals along with the necessary documentation for source approval, as offers lacking this information will not be considered; the deadline for submissions is 45 days from the notice publication date. For further inquiries, interested vendors can contact Michael J. Zuccarini at (215) 697-1106 or via email at MICHAEL.ZUCCARINI@NAVY.MIL.
